LYNCHBURG, Va. (AP) -- -

Public input is being sought on a pollution study of the James River and its tributaries.

A public comment period began Tuesday and runs until April 3.

The total maximum daily load study being conducted by MapTech Inc. examines the amount of bacteria that a body of water can handle to meet federal standards.

The News & Advance ( ) reports that the Virginia Department of Environmental Quality released preliminary findings Tuesday night during a public meeting at Randolph College. The findings show violations in the river, along with tributaries in Amherst, Bedford and Campbell counties, and in Lynchburg.
   Jim Kern with MapTech asked the public for help in identifying sources of pollution discharges, such as straight pipes that release untreated water.
   The study was last completed in 2007.
